So I am working on installing a FP gauge on my truck. The truck had a big line kit on it when I got it. The lines between the lift pump, filter, and injection pump have all been replaced with larger fuel lines and no banjo bolts. I am trying to install a T so I can run the FP gauge off of it with a shut off valve.
My questin is what is the thread pitch of the stock banjo bolts that come out of the fuel filter? I have gone to home depot and a couple auto parts stores trying to match them up, but have not had any luck. Any input would be great.

The stock bolts have metric heads, so I'm guessing they have metric threads also. I doubt the plumbing isle at home despot will have what you're after.

If my memory serves me right I think they are 12 X 1.5 mm

Yes, 12mm x 1.5 is correct.
